Abstract
Description
本発明は、新規なフォトクロミック・ヘテロベンゾピラン(heterobennzopyran)化合物およびこれらを含む製品や組成物に関するものである。
フォトクロミズム(光互変異性/光可逆変色)は、ある種の化学化合物で観察される周知の物理現象である。この現象に関する詳細な解説は、「フォトクロミズム:分子と系」、有機化学40における研究、H.ジュラとH.ボアスーローレンによる編集、エルセビア1990("Photochroism;Molecules and Systems",Studies in Organic Chemistry 40、Edited by H.Durr and H.Bouas−laurent,Elsevier 1990)でなされている。
化合物の種類として、ピラン誘導体は、フォトクロミック効果(光互変効果)を発揮できる化合物として知られている。例えば、米国特許No.5066818号には、新規の可逆フォトクロミック・ナフトピラン化合物が開示されており、これらは、少なくとも1つのオルトー置換フェニル基をピラン環の3の位置で持っている。
この先行アート技術のピランはフォトクロミック化合物を誘導したことについて、例えば米国特許No.5066818号に開示されており、活性化した状態では、比較的単純な吸収プロファイルをみせ(ガウスとロレンジアン曲線(Gaussian and Lorenzian)にみられるように)、そのことからフォトクロミック化合物(光互変異性化合物)そのものが無色である限り比較的純性の色を表わす。多くの商業的適用、特にサングラスの使用に、より中間色の茶色あるいは灰色が必要とされる。この先行技術ピランのフォトクロミック化合物を使用し、より中間色を得るには、2つないし、より多くのフォトクロミック化合物を混ぜる必要がある。これは、価格やこれから紹介する高分子宿主材料(プラスチックホスト材料)に融合(結合)することができるフォトクロミック化合物の容易さという両点において不利なことがある。
本発明者等は、ここでヘテロベンゾピラン(heterobenzopyran)化合物が溶液にあるいは高分子宿主材料に分散された際に、化学線のライト(光)で活性化し、活性化した状況下で中間色、通常茶の色を表わすことを発見した。
したがって、本発明では一般構造式(I)のヘテロベンゾピラン(heterobenzopyran)化合物を提供する。
ここでR1は五員複素環の基を示し、1つあるいはそれ以上のヘテロ原子を含有し、ベンゾピラン骨格のベンゾモイティー(moeity)にあるf−結晶面(f−face)あるいはg−結晶面(g−face)のいずれかに融合し、前記複素環の基中のヘテロ原子は前記ベンゾモイティー(Moeity)に直接結合され、さらに、前記複素環の基はさらなる炭素環式(脂環式)の基あるいは複素環の基と融合したか、あるいは以下で示す構造式R4の基と置換され、
R2とR3の各々は、同一であっても、異なっていてもよく、炭素環式または複素環の基を独立して示し、あるいはR2とR3は、それらに付加された炭素原子とともに炭素環もしくは複素環を形成し、またR4は水素原子あるいはアルキル基、アルコキシ基、アリル基、アリーロキシ基、ヘテロアリル基、ハロゲン基から選択された置換基、あるいは置換されているまたは置換されていないアミノ基、アゾ基、イミノ基、アミド基、エステル基、シアノ基、トリフルオロメチル基、ニトロ基を示す。
疑わしい点がないように、本明細書を通して、ベンゾピラン化合物における環の番号付けの定義については以下の通りとし、
さらに、ベンゾピラン骨格のベンゾ モイティー(moeity)にあるf−結晶面(face)あるいはg−結晶面(face)は炭素原子7と8の間にある結晶面(face)であり、さらにg−結晶面(face)は、前記ベンゾ モイティー(moeity)の炭素原子6と7の間にある。
本明細書を通して、ことわりがない限り、用語「アルキル」は1〜6個の炭素原子を有するアルキル基を意味する。同様に、用語「アルコキシ」は1〜6個の編炭素原子を有するアルコキシ基を意味する。
本発明におけるヘテロベンゾピラン(heterobenzopyran)化合物は非常に複雑な吸収形材(複数の吸収ピーク/くびれ/変曲を有する)を保持し、さらにそのために、溶液やポリマーと融合される際に茶色のような中間色を表わす。
本発明に係わるいくつかの化合物は、まだ分離する準備ができていない異性体の混合物として得られ、しかし他の事例では1つの異性体は主要なものである傾向があり、分離することができる。両事例においても、しかし、本発明者等は、異性体の混合物と単異性体の両方が前記中間色の、通常茶色を表出することができるため、前記の複雑な吸収異形材を得ることが分かった。
好ましくは、環R1にある五員複素環はフラン環、ピロール(pyrolle)環あるいはチオフェン環であり、好ましくはベンゾピラン骨格の7の位置にヘテロ−原子が付与したものである。
R1基における複素環の好ましい置換基は、それに融合されたひとつのベンゼン環、あるいはそれに融合されたサイクロヘキシン環、あるいは複素環の一つ、またはそれ以上のアルキル置換基である。
ピロール(pyrolle)環の事例では、窒素原子はアルキル置換基を、通常メチル基を保持する。
好ましくは、ピラン環におけるR2およびR3置換基はフェニル基、4−トリフルオロメチル−フェニル基、4−アルコキシフェニル基(好ましくは4−メトキシフェニル)、2,4,−ジ(アルコキシ)フェニル基(好ましくは2,4−ジメトキシフェニル)あるいは4−ジアルキルアミノ−フェニル基(好ましくは4−ジメチルアミノ−フェニル)から選択される。
R2およびR3置換基が炭素原子と共に炭素環を形成する際に、それらは好ましくはスピロ−ダイベンゾサイクロヘプテニル(spiro−dibenzocycloheptenyl)置換基、あるいはスピロ−アダマンチル(spiro−adamantyl)置換基あるいはスピロ−ノルボニル(spiro−norbornyl)置換基である。
好ましいR4基は水素あるいはアルキル、通常メチルである。
本発明のベンゾピラン化合物は、次ぎの反応工程式に基づいて一般的な製造法で製造することができる。
本発明のヘテロ・ベンゾピランを形成するために使用されるこの製造法は、比較的良く知られている光互変異性・ベンゾ−およびナフトピラン化合物を生成する方法と非常に類似している。このように周知のベンゾピランとナフトピランの合成についての詳細は、例えばL.メリニ著、「複素環式化学の進歩」、1975、18、159(By L.Merlini in Advances in Heterocyclic Chemistry,1975,18,159)、およびいくつかの特許においても、例えば米国特許NO.5066818号、米国特許NO.4990287号、米国特許NO.4980089号やWO 92/09593にみられる。一般的には、本発明におけるこのヘテロベンゾピラン(heterobenzopyran)は一般構造式(III)のヒドロキシ化合物と一般構造式(IV)のプロパルギルアルコールと酸性のアルミナ(例えばブロックマン指数1のアルミナ)、トリフルオロ酢酸あるいはその他の酸性触媒の存在下における反応により形成され、ヒドロキシ化合物(III)と構造式(IV)のプロパルギアルコールとの間で起きる初期縮合/エステル化反応は、一連の触媒されたシグマトロピック(sigmatropic)の入れ替えや互変異性(tautomerisation)により補助され、必要な構造式(I)の化合物を得る。
本発明のヘテロベンゾピラン(heterobenzopyran)化合物を生成するこの合成プロセスは、以下の反応工程式で図示されているように、式(I A)および(I A)の2つの異性体ヘテロベンゾピラン(heterobenzopyran)の形成を導くことが可能である。
ヒドロキシ化合物(III)とプロパギルアルコール(IV)の反応は構造式(V)のアリルプロパルギルエーテルの初期の形成により起り、次ぎにクライゼンのような[3,3]−シグマトロピック(sigmatropic)再配置が成される。構造式(III)化合物のヒドロキシ基の両端の0位置に置換基がない場合には、クライゼンのような[3,3]−シグマトロピック(sigmatropic)再配置は式(VI A)および(VI B)2つの異性体中間体をもたらし、これらの中間体はその後[1,5]−シグマトロピック(sigmatropic)シフトを式(I A)および(I B)の2つの異性体ヘトロベンゾピラン化合物を形成するために行う。
構造式(III)の化合物におけるベンゼン環の融合されたモイテイー(moieties)あるいは置換基の存在は、2つの異性体(I A)および(I B)の内の1つの主成分化に導くことができ、それはヘテロベンゾピラン(heterobenzopyran)異性体の異性体率が構造式(V)におけるアリルプロパルギルエテールの環化(cyclisation)のレジオ選択性に影響されるためである。
この構造式(III)のヒドロキシ化合物は商業上入手できる化合物であり、あるいは公知の合成法により、あるいはこれらの公知の合成法から得られた方法のいずれかによるものである。
例えば、以下の実施例8の出発原料である5−ヒドロキシ−2、3−ジメチルベンゾチオフィン(dimethlbenzothiophene)は、S.グロノウィッツ他、「アクタ薬物学、Suec.、1987、15、337(by S.Gronowitz et al.(Acta.Pharm.Suec.1987,15,337)において記載されている方法と類似し、2−ジメチルベンゾチオフィン(dimethlbenzothiophene)を製造する。このように、5−ブロモ−1,3−ジメチルベンゾオフィン(dimethlbenzothiophene)はn−BuLiを5−リチュウム化合物に使用して生産され、(n−BuO)3Bと反応し、対応するトリ−ブチルホウ酸誘導体を形成するために反応され、その後必要とされる5−ヒドロキシ−2、3−ジメチルチオフィン(dimethyl thiopene)を得るためにH2O2が加えられる。
本発明において、一般構造式(IV)のプロパルギルアルコールを使用しヘテロベンゾピラン(heterobenzopyran)化合物の製造法は周知のものであり、この例としてT.F.ラットレジ著「アチレンニック化合物」レインホルド、ニューヨーク、1968(By T.f.Rutledge in Acetylenic Compounds,Reinhold,New York 1968)に記載されているとおりである。
本発明におけるこの新規なヘテロベンゾピラン(heterobenzopyran)化合物は、前記高分子宿主材料にフォトクロモック特性を与えるために、当該高分子宿主材料に混合されるフォトクロミック材料として特に有用であることが見い出されている。
本発明におけるこの新規なヘテロベンゾピラン(heterobenzopyran)化合物は、公知の方法でプラスチックの宿主ホスト材料に混合されており、この例として欧州特許0245020号あるいは米国特許5066818号に記載されている。
本発明における材料は、暗い状況下で黄茶、赤茶、オリーブグリーンの色を示す。色あせたか、あるいは白くなった条件において、この材料は青色(無色)か、あるいは淡い色彩を示す。
典型的な高分子宿主材料は光学的に透明なポリオール(アリルカーボネート)モノマーの重合体のような高分子材料、ポリメチールメタクリレート、セルローズアセテート、セルローズトリアセテート、セルローズトリアセテートプロピオネート、セルローズトリアセテートブチレート、ポリ(酢酸ビニル)、ポリ(ビニールアルコール)、ポリウレタン、ポリカーボネート、ポリエチレンテレフタレート、ポリスチレン、スチレン/メチルメタクリレート共重合体、スチレン/アクリロニトリル共重合体、およびポリビニールブチラールなどのようなポリアクリラートである。透明なコポリマー(共重合体)と、その透明なポリマーの混合物もまた宿主材料として好適である。ヨーロッパ特許No.0294056号またはヨーロッパ特許No.0453149号に記載されているポリマーもまた好適である。
好ましくは、高分子宿主材料は、ポリウレタン、あるいはジエチレングリコールビス(アリルカーボネート)(商品名;CR−39で販売されている)のポリマー、あるいはスペクトラリッテ(SPECTRALITE)−ソーラ・オプティカル・米国(Sola optical U.S.A.)により販売された材料の如き光学的に透明な重合された有機材料がある。
通常、フォトクロミック・スピロ・オキサジン化合物の量は、重量換算で、0.001〜0.5重量%の割合で高分子宿主材料に混連される。
いくつかの出願では、まとまった色の効果を得るため、本発明のスピロ−オキザジン化合物を、他のフォトクロミック材料と併合することが好ましく、有利である。例えば、スピロ−オキサジンは530〜680nmの色の範囲を有しており、これは暗い状況下でスピロ−オキサジンが、赤紫、紫、青、青緑もしくは緑のような色合いを宿主材料与えるということを意味する。このように、本発明におけるナフトピラン化合物はとしては、本発明者等のヨーロッパ特許No.0245020号、もしくは英国特許No.92/25346号、英国特許No.92/25347号および英国特許No.92/25348号に記載した化合物のようなスピロ−オキサジン材料を知ることができ、また米国特許No.4637698号、米国特許No.3562172号、米国特許No.3578602号、米国特許No.4816584号、米国特許No.4215010号、及び米国特許No.4342668号に記載されたスピロ(インドリーノ)ナフトキサジン、スピロ(インドリーノ)ピリドベンゾキサジンおよびスピロ(インドリーノ)ベンゾキサジンのような化合物を知ることができ、このような他のフォトクロミック材料と組み合わせることができる。本発明における化合物は我々の英国特許No.9306587、あるいは米国特許No.5066818に示されるように、ナフトピラン化合物のような他のフォトクロミック材料とも組み合わせることができる。
通常、組み合わせて使用する際は、さらに追加するフォトクロミック材料は、高分子宿主材料の重量に基づいて、0.001〜0.5重量%の量で存在する。
本発明のスピロ−オキサジン化合物を混合したフォトクロミック・プラスチック品の好適な使用例としては、例えば、サングラスや眼科用レンズのような平面レンズ、自動車や航空機のような運送手段用のフォトクロミック透明体等の製造が挙げられる。

The present invention relates to novel photochromic heterobenzopyran compounds and products and compositions containing them.
Photochromism (phototautomerism / photoreversible discoloration) is a well-known physical phenomenon observed with certain chemical compounds. For a detailed explanation of this phenomenon, see “Photochromism: Molecules and Systems”, Research in Organic Chemistry 40, edited by H. Jura and H. Boas-Loren, Elsevier 1990 (“Photochroism; Molecules and Systems”, Studies in Organic Chemistry 40 Edited by H. Durr and H. Bouas-laurent, Elsevier 1990).
As a type of compound, a pyran derivative is known as a compound that can exhibit a photochromic effect (photochromic effect). For example, US Patent No. 5066818 discloses novel reversible photochromic naphthopyran compounds, which have at least one ortho-substituted phenyl group at position 3 of the pyran ring.
The prior art pyran, for example, disclosed photochromic compounds is disclosed, for example, in U.S. Pat. No. 5066818, which, when activated, shows a relatively simple absorption profile (Gaussian and Lorenzian curves). Therefore, as long as the photochromic compound (phototautomeric compound) itself is colorless, it exhibits a relatively pure color. For many commercial applications, especially the use of sunglasses, more neutral browns or grays are required. In order to obtain more neutral colors using this prior art pyran photochromic compound, it is necessary to mix two or more photochromic compounds. This may be disadvantageous in terms of both cost and ease of photochromic compounds that can be fused (bonded) to the polymer host material (plastic host material) to be introduced.
Here, the present inventors, when a heterobenzopyran compound is dispersed in a solution or a polymeric host material, are activated with actinic light (light), and in the activated state, an intermediate color, usually I discovered that it represents the color of tea.
Accordingly, the present invention provides a heterobenzopyran compound of general structural formula (I).
Here, R 1 represents a 5-membered heterocyclic group, contains one or more heteroatoms, and is in the benzopyran skeleton moeity f-face or g-crystal. Fused to any of the g-faces, heteroatoms in the heterocyclic group are directly bonded to the benzomoiety, and further the heterocyclic group is further carbocyclic (alicyclic) A group of formula) or a heterocyclic group, or substituted with a group of structural formula R 4 shown below,
Each of R 2 and R 3 may be the same or different and independently represents a carbocyclic or heterocyclic group, or R 2 and R 3 are carbon atoms attached to them. Together with R 4 is a hydrogen atom or a substituent selected from alkyl, alkoxy, allyl, aryloxy, heteroallyl, and halogen, or substituted or substituted. No amino group, azo group, imino group, amide group, ester group, cyano group, trifluoromethyl group, nitro group.
Throughout this specification, the definition of ring numbering in benzopyran compounds is defined as follows so that there is no doubt.
Further, the f-crystal face or the g-crystal face in the benzomoyity of the benzopyran skeleton is a crystal face between the carbon atoms 7 and 8, and the g-crystal face. (Face) is between carbon atoms 6 and 7 of the benzo moeity.
Throughout this specification, unless stated otherwise, the term “alkyl” means an alkyl group having from 1 to 6 carbon atoms. Similarly, the term “alkoxy” means an alkoxy group having from 1 to 6 knitted carbon atoms.
The heterobenzopyran compound in the present invention retains a very complex absorption profile (having multiple absorption peaks / neckings / inflections) and, therefore, a brown color when fused with a solution or polymer. Such intermediate colors are represented.
Some compounds according to the invention are obtained as a mixture of isomers that are not yet ready for separation, but in other cases one isomer tends to be the major one and can be separated. . In both cases, however, the inventors are able to obtain the complex absorbing profile because both the mixture of isomers and the single isomer can express the neutral color, usually brown. I understood.
Preferably, the five-membered heterocyclic ring in the ring R 1 is a furan ring, a pyrrole ring or a thiophene ring, and preferably a hetero-atom is added to position 7 of the benzopyran skeleton.
Preferred substituents for the heterocyclic ring in the R 1 group are one benzene ring fused thereto, a cyclohexyne ring fused thereto, or one or more alkyl substituents of the heterocyclic ring.
In the case of the pyrrole ring, the nitrogen atom carries an alkyl substituent, usually a methyl group.
Preferably, the R 2 and R 3 substituents on the pyran ring are phenyl, 4-trifluoromethyl-phenyl, 4-alkoxyphenyl (preferably 4-methoxyphenyl), 2,4, -di (alkoxy) phenyl. It is selected from a group (preferably 2,4-dimethoxyphenyl) or a 4-dialkylamino-phenyl group (preferably 4-dimethylamino-phenyl).
When the R 2 and R 3 substituents form a carbocyclic ring with carbon atoms, they are preferably spiro-dibenzocycloheptenyl substituents, or spiro-adamantyl substituents or Spiro-norbornyl substituent.
Preferred R 4 groups are hydrogen or alkyl, usually methyl.
The benzopyran compound of the present invention can be produced by a general production method based on the following reaction process formula.
This process used to form the hetero-benzopyrans of the present invention is very similar to the process of producing relatively well known phototautomeric benzo- and naphthopyran compounds. Details of such well-known syntheses of benzopyran and naphthopyran are described in, for example, L. Merini, “Advances in Heterocyclic Chemistry”, 1975, 18, 159 (By L. Merlini in Advances in Heterocyclic Chemistry, 1975, 18, 159). , And several patents, for example, in US Patent No. 5066818, US Patent No. 4990287, US Patent No. 4980089 and WO 92/09593. Generally, the heterobenzopyran in the present invention is a hydroxy compound of the general structural formula (III), a propargyl alcohol of the general structural formula (IV), an acidic alumina (for example, an alumina having a Brockman index of 1), The initial condensation / esterification reaction formed between the hydroxy compound (III) and the propargy alcohol of the structural formula (IV), formed by reaction in the presence of fluoroacetic acid or other acidic catalyst, is a series of catalyzed sigma Assisted by sigmatropic replacement and tautomerisation, the required compound of structural formula (I) is obtained.
This synthetic process to produce the heterobenzopyran compounds of the present invention is represented by the two isomeric heterobenzopyrans of formula (IA) and (IA), as illustrated in the following reaction scheme: It is possible to guide the formation of
The reaction of hydroxy compound (III) with propargyl alcohol (IV) occurs by the initial formation of allyl propargyl ether of structural formula (V), followed by Claisen-like [3,3] -sigmatropic rearrangement Is made. When there is no substituent at the 0 position on both ends of the hydroxy group of the structural formula (III) compound, the Claisen-like [3,3] -sigmatropic rearrangement can be represented by the formulas (VI A) and (VI B ) Resulting in two isomeric intermediates, which then undergo a [1,5] -sigmatropic shift to form the two isomeric hetrobenzopyran compounds of formulas (IA) and (IB) To do.
The presence of fused moieties or substituents on the benzene ring in the compound of structural formula (III) can lead to one of the two isomers (IA) and (IB) as the main component, This is because the isomer ratio of the heterobenzopyran isomer is influenced by the regioselectivity of cyclisation of allylpropargyl ether in the structural formula (V).
The hydroxy compound of the structural formula (III) is a commercially available compound, or is either by a known synthesis method or by a method obtained from these known synthesis methods.
For example, 5-hydroxy-2,3-dimethylbenzothiophene, which is the starting material of Example 8 below, can be obtained from S. Gronowitz et al., “Acta Pharmacology, Suec., 1987, 15, 337 (by S Similar to the method described in Gronowitz et al. (Acta. Pharm. Suec. 1987, 15, 337), 2-dimethylbenzothiophene is prepared, thus 5-bromo-1,3 -Dimethyllbenzothiophene is produced using n-BuLi as a 5-lithium compound, reacted with (n-BuO) 3B and reacted to form the corresponding tri-butyl boric acid derivative, then H 2 O 2 is added to obtain the required 5-hydroxy-2,3-dimethyl thiopene.
In the present invention, a method for producing a heterobenzopyran compound using propargyl alcohol of the general structural formula (IV) is well known, and examples thereof include “Athyleneic Compound” by TF Ratresi, Reynhold, New York, 1968 (By TfRutledge in Acetylenic Compounds, Reinhold, New York 1968).
This novel heterobenzopyran compound in the present invention has been found to be particularly useful as a photochromic material mixed with the polymeric host material in order to impart photochromic properties to the polymeric host material. ing.
This novel heterobenzopyran compound in the present invention is mixed in a known manner with a plastic host host material, examples of which are described in European Patent 0450520 or US Pat. No. 5,668,818.
The material in the present invention exhibits yellow brown, red brown and olive green colors under dark conditions. In the faded or whitened condition, this material is blue (colorless) or shows a pale color.
Typical polymeric host materials are polymeric materials such as polymers of optically clear polyol (allyl carbonate) monomers, polymethyl methacrylate, cellulose acetate, cellulose triacetate, cellulose triacetate propionate, cellulose triacetate butyrate, Polyacrylates such as poly (vinyl acetate), poly (vinyl alcohol), polyurethane, polycarbonate, polyethylene terephthalate, polystyrene, styrene / methyl methacrylate copolymers, styrene / acrylonitrile copolymers, polyvinyl butyral, and the like. Transparent copolymers (copolymers) and mixtures of the transparent polymers are also suitable as host materials. Polymers described in European Patent No. 0294056 or European Patent No. 0453149 are also suitable.
Preferably, the polymeric host material is polyurethane or a polymer of diethylene glycol bis (allyl carbonate) (sold under the trade name CR-39) or SPECTRALITE-Sola optical USA There are optically transparent polymerized organic materials such as those sold by).
Usually, the amount of the photochromic spiro oxazine compound is mixed with the polymer host material at a rate of 0.001 to 0.5% by weight in terms of weight.
In some applications, it is preferred and advantageous to combine the spiro-oxazine compounds of the present invention with other photochromic materials in order to obtain a unified color effect. For example, spiro-oxazine has a color range of 530 to 680 nm, which means that under dark conditions spiro-oxazine gives host materials shades such as magenta, purple, blue, blue-green or green. Means that. Thus, the naphthopyran compounds in the present invention include the European Patent No. 0245020 of the present inventors, British Patent No. 92/25346, British Patent No. 92/25347 and British Patent No. 92 / Spiro-oxazine materials, such as the compounds described in US Pat. No. 25348, can also be found, and U.S. Pat.No. 4637698, U.S. Pat.No. 3356217, U.S. Pat.No. 33578602, U.S. Pat.

No.4342668, Such other photochromic materials can be combined. The compounds in the present invention can also be combined with other photochromic materials such as naphthopyran compounds, as shown in our British Patent No.9306587 or US Pat. No. 5066818.
Usually, when used in combination, the additional photochromic material is present in an amount of 0.001 to 0.5% by weight, based on the weight of the polymeric host material.
Examples of suitable use of the photochromic plastic product in which the spiro-oxazine compound of the present invention is mixed include, for example, a planar lens such as sunglasses and an ophthalmic lens, a photochromic transparent body for transportation means such as an automobile and an aircraft, etc. Manufacturing is mentioned.
